What’s next? A Colored Kindle?

Despite Amazon’s promise to reinvent the newspaper and magazine industry with its new, large-screen Kindle DX electronic reader, some people may be reluctant to embrace the technology until full-color displays are possible. A new approach developed by Philips now offers fresh hope for color e-paper displays that are so bright and clear that even traditional liquid crystal displays (LCDs) will pale in comparison.

According to Kars-Michiel Lenssen, who headed the work at Philips Research, based in Eindhoven, in the Netherlands, the new approach has the potential to create color images that are three times brighter than displays that use color filters, including LCDs. “This is the closest an electronic-paper technology ever got to printed paper,” he says.

Color displays normally require four subpixels–red, green, blue, and white–to create each full-color pixel. “That costs you in terms of resolution,” says Pieter van Lieshout, head of product research and development for Polymer Vision, which was spun off from Philips Electronics three years ago to develop flexible electronic-paper displays.
